Fanaa (2006)

Zooni Ali Beg (Kajol) is a blind Kashmiri girl who travels without her parents for the first time with a dance troupe to Delhi to perform in a ceremony for Republic Day. On her journey, she meets Rehan Khan (Aamir Khan), a Casanova tour guide who flirts with her. Although her friends warn Zooni about him, she cannot resist falling in love.

On her last night in Delhi, Rehan and Zooni sleep together. As Zooni is leaving the next day on a train, Rehan comes in and takes her away with him. Her parents arrive in Delhi to marry them. Zooni has a procedure done that helps her see again, but when she comes out of surgery, she finds out that Rehan was killed in a bomb blast in the city, and is heartbroken.

Meanwhile, Malini Tyagi (Tabu) is a special intelligence agent brought in to assess the threat of the bomb blast, and the group responsible, IKF. She believes it is the work of one man who is helping IKF. It is revealed that man is Rehan, who put the bomb blast in motion, then faked his death so Zooni wouldn't come looking for him. He privately admits that he loves Zooni, but also concedes that he can never see her again because of his dangerous life.

Seven years later, Rehan is in an Indian army camp on another mission for the IKF looking to get a hold of the trigger of a bomb in the army's possession. He manages to steal it, but Tyagi has figured out his plan and sends forces to stop him after he acquires the trigger. In the ensuing shootout, Rehan is injured severely.

He makes his way to a remote house looking for help. The door opens, and it turns out to be Zooni's house. It's also revealed that Zooni had given birth to Rehan's son after Rehan's supposed death and named her son 'Rehan' after his father. Zooni and her father manage to save Rehan, though neither knows his real identity. Though initially distant from them, Rehan develops an affection for his son and becomes friendly towards Zooni and her father.

Rehan reveals his true identity to the two of them. Initially hurt, Zooni refuses to let Rehan leave her again, and the two of them are married by her father. Tyagi has a report published about Rehan, warning the public that he is a dangerous terrorist. Zooni's father sees this report, and realizes that it's Rehan. He holds him at gunpoint, but Rehan thwarts him and manages to get the trigger back.

In the process, though, he accidentally throws Zooni's father off a ledge, killing him, something Rehan regrets. He radios the IKF from an army officer's house describing his position. However, the officer discovers Rehan, who then kills the officer.

Zooni finds her father's body later, and when she tries to tell Rehan, he covers. However, Zooni later sees the news report, and finds the trigger. She takes young Rehan and the trigger, and goes to the officer's house. When she finds blood there, she radios for help, and gets in touch with Tyagi, who tells her to stop Rehan at any cost. Rehan arrives at the house the next day, and tries to convince Zooni to hand over the trigger.

He takes it from her, saying the IKF will kill her and their son if he doesn't. Zooni, though, follows him outside when the IKF arrives and shoots him. Rehan draws his gun on Zooni, but can't bring himself to shoot her. Zooni shoots him again to stop him. Tyagi arrives and stops the IKF from shooting Zooni. Rehan dies in Zooni's arms.

Zooni and young Rehan later visit the graves of both her father and Rehan Sr., who are buried next to each other. When Rehan asks if his father was wrong, Zooni tells her son that his father did what he thought was right. Both Zooni and young Rehan tell Rehan Sr. that they love him before leaving.
